What is acquired haemophilia?
Acquired haemophilia is a rare condition that it is thought to occur in only 1-2 people in a million. It can affect males and females, unlike hereditary haemophilia, which affects mostly males. In hereditary haemophilia, an affected gene either partially or totally prevents the production of the clotting factor (click here for more information). In contrast, in acquired haemophilia, the immune system believes the bodys own clotting factor is foreign and makes antibodies, known as inhibitors, which neutralise it.
